The Effect Of Elevated Glucose On Neutrophilic Phagocytosis In Genetically Diabetic Mice, Larry B. Thompson

Loma Linda University Electronic Theses, Dissertations & Projects

Infiltration to an injury site or area of bacterial contamination by polymorphonuclear leucocytes (or neutrophils) is an early and essential phase of the early inflammatory reaction. Their action on foreign matter is the most critical step taken by body defense mechanisms in the first 24 hours. Anything which interferes with that action, phagocytosis, greatly hampers early inflammation. This study was designed to see the effect of elevated glucose levels on neutrophil phagocytosis in a unique strain of genetically diabetic mice.

Twenty-two diabetic and twenty-four control female mice were used. Blood glucose determinations and total white counts were made on each …

A Clinical And Microscopic Evaluation Of Plaque Removal And By The Hydrodent Brush, Soertini E. Lambri

Loma Linda University Electronic Theses, Dissertations & Projects

The Hydrodent toothbrush was compared to conventional toothbrush (Lactona # 19) in its effectiveness on removing the plaque, eliminating the pocket depth, and improving the gingival tissue condition.

Forty six male and female subjects with the age range of 18 to 50 years old participated in a 5 month study with 4 week intervals. Each subject received a Hydrodent brush of soft, medium, and hard textures and a conventional toothbrush. The toothbrushes were given randomly and the subject served as his own control.

Clinical and histological evaluations were made after the use of each toothbrush. The clinical evaluation showed some …

The Response Of Gingival Tissues To Alterations In Ph, Robert C. Jann

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was to evaluate the histopathological and clinical changes that occurred when a continuous supply of exogenous acid or base, at varying pH, was delivered adjacent to the gingival crest of the monkey. A related goal was to develop a monkey model system which would deliver test solutions continuously and atraumatically, to the experimental gingival sites.

Two young adult female monkeys had a perfusion apparatus attached to certain maxillary teeth so that test solutions were deposited atraumatically to the marginal gingival tissues. During the experimental periods the animals were kept in primate restraining chairs and fed …

An In Vivo Perfusion Apparatus For Studies On Gingival Disease In The Albino Rat : Assessment By A Perfusion Of The Enzymes Collagenase And Hyaluronidase, James A. Smith

Loma Linda University Electronic Theses, Dissertations & Projects

This thesis describes an in vivo perfusion apparatus which can continuously deliver controlled quantities of solutions to localized, contralateral intraoral areas in albino rats. Three animals were per fused on the experimental area (the mesial sulcular area of the maxillary first molar) on one side with tap water and Trypan blue. Localization of the solution delivered and minimal histological changes due to the presence of the apparatus was demonstrated on these animals. Solutions of .5%, 1%, and 2% hyaluronidase and collagenase were perfused on the experimental areas of nine animals. When both enzymes were used, hyaluronidase always preceded collagenase in …

Periodontal Pocket Reduction Following Gingival Curettage, Robert B. Tandy

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was to evaluate pocket reduction following gingival curettage. The effects of temporary pressure packing, inflammation, oral hygiene, pocket depth, age and sex of the patient were evaluated.

Three hundred twenty-eight periodontal pockets were studied in forty-one adult patients selected with interdental lesions ranging from 3.0 - 7.5 mm. in depth. Pocket depth and gingival height were measured preoperatively, one month postoperatively and two months postoperatively. The mean change in pocket depth and gingival height was calculated and statistical significance was determined for all measurements.

The results show that after a two-month postoperative evaluation following gingival …

The Effect Of A Patient-Counseling Film And Hygienist On The Oral Hygiene Of Junior High School Students, Leonard L. Espinda

Loma Linda University Electronic Theses, Dissertations & Projects

The effect of a single viewing of a patient-counseling film and a single instruction by a hygienist in producing changes in the oral hygiene of a group of school children 12 to 13 years of age was investigated. The subjects were divided into three experimental groups and one control group of twenty-one each.

A different method of oral hygiene instructions was given to each of the experimental groups. One group viewed the film, the second group was instructed by a hygienist, and the third group viewed the film and was instructed by the hygienist. The control group was not given …

An In Vivo Perfusion Apparatus For Studies On Gingival Disease : Assessment By A Perfusion Of Nonspecific Proteolytic Enzymes, Don Dornan

Loma Linda University Electronic Theses, Dissertations & Projects

This thesis describes an in vivo perfusion apparatus which can continuously deliver controlled quantities of solutions to localized, contralateral intra oral areas in albino rats. Three animals were per fused on the experimental area (the mesial sulcular area of the maxillary first molar) on one side with tap water and trypan blue. Localization of the solution delivered and minimal histological changes due to the presence of the apparatus was demonstrated on these animals. A 1% solution of trypsin was perfused on the experimental area of one animal for one day at the rate of 4.8 ml/day and on another animal …

A Study Of Alveolar Bone Loss And Two-Hour Postprandial Blood Sugar Levels, R. Leslie Arnett

Loma Linda University Electronic Theses, Dissertations & Projects

Two-hour postprandial blood sugar determinations were carried out on 500 patients referred for periodontal care. The mean percentage of alveolar bone loss around the mandibular bicuspid teeth was established for each individual. The subjects were then grouped according to blood sugar levels and the mean alveolar bone loss was calculated. The group was separated into male and female sub-groups and data was computed for these segments as well as the total sample. The data was evaluated in a similar manner for those subjects between 40 and 49 years of age.

No Chi-square determinations were statistically significant but significance in differences …

The Effect Of Glucose On Neutrophilic Phagocytosis, Donald F. Adams

Loma Linda University Electronic Theses, Dissertations & Projects

Samples of blood were obtained from thirty healthy young adult males (Loma Linda University School of Dentistry), and contaminated with bacteria. Varying concentrations of pure glucose were added to this mixture to observe the effect of the glucose on in vitro neutrophilic phagocytosis. As the glucose levels increased a statistically significant suppression was noted in the ability of the neutrophilic leukocytes to engulf Staphylococcus epidermidis.

It was not possible, however, to predict the degree of suppression for any particular level of glucose added nor is it possible to state that suppression will occur in any one individual.

Two methods of …

The Pathogenesis Of Periodontal Disease And Treatment Implications, Richard C. Oliver

Loma Linda University Electronic Theses, Dissertations & Projects

Presently accepted concepts of the etiology and pathogenesis of periodontal disease do not adequately explain the following consistent clinical observations: (1) equal local etiologic factors do not result in equal periodontal destruction in all patients; and, (2) equal therapy is not equally successful in all patients. The differences in patient response must be due to differences within the patient. By relating the broadened concept of disease, as described by Engel, to periodontal disease, the reasons for these individual patient differences become apparent. This concept consideres[sic] disease in relation to the patient's genie and developmental background, as well as the present …
